"I feel that it's important that the Little Bellas who ride these bikes are reminded to never be afraid, and to go kick some butt going after what they love."— Kayla Clarot, Specialized Women's Graphic Designer. Partnering with Little Bellas, we've created a Limited Edition Women's Pitch to honor, encourage, and empower girls to ride bikes. Together, the Women's Mountain Bike Team developed this custom bike to represent a concept developed exclusively for Little Bellas—Dream in Color. The design will help your little one find their inner spirit animal with a sticker pack of creatures that all have matriarchal, or gender-equal, roles.

Say hello to Surly's rowdy, trail-shredding Instigator 2.0. The no-nonsense chromoly frame is made for charging hard and going big. It's super tough, yet handles nimbly and accelerates like mad. The heart of the bike is Surly's 26+ platform which has clearance for 50mm-wide rims and 2.75-inch tires, so you get endless traction and the rollover-action of a 27.5-inch wheel, coupled with the snappy, go-fast responsiveness of a 26-incher. The geometry is dialed for a 140mm travel suspension fork and features a long top tube and short rear end for more of the same fun. And this thing is versatile, the frame comes with dropouts for rolling singlespeed, or geared with a quick release or a 142x12mm through-axle with a Shimano direct-mount hanger.

It's been said that variety is the spice of life, and the same could be said for riding. After all, life's too short to spend all of your time out on the bike path.

It’s the bike you turn to when you’re not entirely sure what the night has in store. It’s the bike to grab when you want to have just as much fun riding to the trail as you do on the trail, itself. Singlespeeding is an integral part of Surly’s DNA, and the Lowside continues the tradition, by taking a simpler approach to trail riding.

We know that picking a mountain bike can be a bit of daunting process, with all of the options and technology floating around out there and everything. But while some suspension platforms and tech pass like fads in the wind, hardtails have stuck around since the advent of the mountain bike. That's why we built our Pitch Sport 27.5 around an aluminum hardtail design. The design allows the rear end to stay planted while you're pedaling, so it has plenty to offer in the way of efficiency on climbs and on the flats. And with our acclaimed Sport Trail 27.5 Geometry and ample suspension up front, you're guaranteed to feel confident and ready to rip when the trail tips downwards. It's everything you need to get there and get riding.

Off-road touring can be a zesty enterprise, but it’s not without its perils. Bicycles are simple machines that are extremely efficient, but all simple machines carry along with them the chance of breaking down. This efficiency can get you in trouble if your bike decides to break down far away from the comforts of your parent’s basement. If you’re going to ride your bicycles where no one can see, you better take gear that’s up to the task.
Troll is up to the task. Surly's Troll was once a simple mountain bike frame with a few extras that made it nice for touring. The Troll has evolved into a frame that has been pushed deeper into the category of off-road touring. Its geometry is no longer suspension corrected, which gives it more room for a larger frame bag. The chainstay yoke has been redesigned to be fully compatible with 26+ tires and comes with the always-comfy Jones Loop bar. The dropouts still allow you to run disc brakes, fenders, a Rohloff hub, and racks simultaneously. It also comes with more braze-ons than you thought possible – there are four triple bottle mounts on the fork alone (don’t get excited, you can only run one Anything Cage per fork leg), as well as two more triple bottle mounts on the down tube. Troll is a bike that has one purpose – and that purpose is to carry you as far away from society as possible.

Wednesday is a frame with a decade of Surly's Omniterra design experience distilled into one steel package. Wednesday can ride over the same type of pretty much anything all of their other Omniterra bikes can, but they borrowed elements from both their Trail and Touring categories to create an Omniterra ride that can truly handle anything you want to attempt. Want to point the thing down a mountain and roll those dice? Wednesday has geometry spry enough to get you through the techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish when you have to ride back to the top. It also has the chops for any sort of expedition you may want to undertake. It has plenty of bottle mounts; triple bottle bosses on both fork legs and the down tube; standard bottle mounts on the seat tube and underside of the down tube; plus rack mounts on the frame and fork and fender eyelets on the dropouts, along with barrel bosses on the crown, fork legs and mid-blade, thru-blade eyelets on the fork as well. It also has internal dropper post routing and Surly Trip Guides to manage all the housing and cables on your frame with style. Wednesday also has its very own dropout design as well – a rear-facing, slotted dropout that can use either 10mm or 12mm axles and exit rearward or vertically. They’re cast steel and spaced at 170/177mm. Wednesday gives you a lot of options in the tire clearance category. In the full-forward, short chainstay position you can run 26 x 3.8? tires on 80mm rims and in the full-rearward, longer chainstay position you get the option of 26 x 4.6? tires on an 80mm rim. Wednesday is made out of Surly's own proprietary 4130 CroMoly steel and is ED coated for extra protection from the elements.

The Wednesday is the result of over a decade of Omniterra design experience distilled into one steel package. It can easily ride over or through most anything our other Omniterra bikes can and then some. With the Wednesday Frameset, Surly borrowed elements from some of their Trail and Touring models to create an Omniterra whip that can truly handle anything you want to attempt. Want to point it down the side of mountain? Go ahead, roll those dice. And if you make it to the bottom, you’ll be able to ride back to the top for round two. Wednesday’s geometry is spry enough to get you through techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish on terrain-crawling stuff.
While Wednesday is plenty confident on terrifying terrain, it also has the chops for any sort of expedition you may want to undertake. Surly gave it all the necessary braze-ons and mounts for whatever accoutrements you feel necessary in your travels. Racks? Front and rear, friend. Fenders? You got it. Bottle mounts? How does triple bottle bosses on both fork legs and the down tube, and two sets of standard mounts on the main triangle grab you? They even gave Wednesday internal routing for a dropper post and Surly Trip Guides to keep everything nice and neat and free of rat’s nests. In the dropout department, Wednesday uses a cast steel, rear-facing, slotted dropout that can exit either rearward or vertically. They’re compatible with either 10mm or 12mm axles and are spaced at 170/177mm.

Years ago the Karate Monkey helped start the 29” wheel movement and, as time’s gone by, many companies ­– Surly included – have experimented with even more wheel sizes.
With so many different types and sizes of tires now on the market, riders have begun to understand the effect that tire width has on overall wheel diameter, and with ample tire clearance, you can see the benefits of multiple wheel sizes all on one bike. 27+ tires have the same rolling diameter as a 29” wheel, yet you get all the traction and flotation benefits of extra-wide knobbies. And that’s just the tires.
The Karate Monkey frame has recently gotten a make over that includes the addition of features like internal dropper post routing, a new tubeset that uses the same trumpet tubes found on our Instigator 2.0, and a slight tweak in geometry that is more progressive and trail-oriented. The Karate Monkey uses a horizontal dropout with a derailleur hanger that features Gnot-Boost spacing, which gives the rider the ability to run any kind of mountain bike hub they choose. 10 x 135mm QR, 12 x 142, or 12 x 148 Boost will all work in the Karate Monkey frame. The frame uses a 44mm headtube for broad fork compatibility and is ED coated for an added layer of internal protection. If, at any point, you decide you want to throw on some skinny meats, standard 29” wheels and tires can be swapped in with no issue. If you want to round-house kick some trail right in the face, the Karate Monkey is your sled.

Surly's Krampus rolls fast, holds speed, and devours corners. It's designed for 29 x 3-inch tires, offering increased traction, incredible float, huge rollover, and low-fi suspension to take your trail ride to new heights of fun. Surly built this frame and fork out of tapered and butted chromoly and gave the frame a long top tube and short chainstays, so it's playful, smooth, versatile, and durable. Boost front spacing keeps you current with the latest MTB tech, and, "Gnot Boost," rear spacing means you can run any the rear hub you want: 135 x 10 QR, 142 x 12mm, or 148 x 12mm thru axles. This frameset also offers internal dropper post routing so you're granted a license to get rowdy, which you really can't help but do on a Krampus.

If you’re like us, your bike needs will likely change by the day, week, month or year. Ogre will get you to your job during the week, then way out of town on the weekend. It even has the chops to handle a cross-country trek or nine. It’s not sluggish on pavement or gravel and can also hold its own on singletrack. Ogre is designed to be the ultimate steel utility vehicle. It relishes in those “take-the-long-way-home-and-find-some-beverages-along-the-way” sort of commutes. You can also haul enough crap on it that you don’t even have to go home if you don’t want to.
For this year, we simplified Ogre a bit. We removed the canti studs, so it is now a disc brake-only beast. Now, before you start yelling at us about how the canti studs were the only reason you were even considering buying an Ogre and now we’ve left you contemplating your very existence in this ultimately-doomed universe, hear us out. Rim brake 29er rims — like the ones that you would need to have to make use of those canti studs in the first place — are becoming increasingly harder to find. We could have given you a feature that you’d end up not really being able to use in the future but what kind of monsters do you think we are? To quench your unquenchable thirst for rim brakes, check out the Troll.
As far as other updates to the frame go, that about sums it up. Ogre still has everything else you’ve come to know and love: two water bottle mounts, four sets of three-pack bosses, mid- and low-blade fork eyelets, threaded holes for racks, fenders, and trailer mounting nuts, and a Rohloff OEM2 axle plate slot. It still features horizontal-slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefy tire clearance. It’s still fully compatible with both 29 x 2.5” and 27.5+ tires. In the complete bike version, we’ve opted to go with a 1x drivetrain and a flat handlebar.
We typically try to avoid BS cliché terms like “Do-It-All” or “Swiss Army Knife of Bikes”, so we’ll just say that Ogre can probably handle most of the ideas that are bouncing around in your head.

If you’re like us, your bike needs will likely change by the day, week, month, or year. Surly's Ogre can get you to your job during the week, then way out of town on the weekend. The latest version of the Ogre has received some fantastic updates, including horizontal slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefier tire clearance — all in a 29er/27.5+ platform. Ride it any day of the week; it’s not sluggish on pavement or gravel and can also hold its own on singletrack.
- Gnot-Boost spacing allows the use of 135mm QR hub, 142 x 12mm thru-axle, or 148 x 12mm Boost hubs.
- Full-length Surly Trip Guide housing line guides for derailleurs and brakes
- Two sets of bottle cage mounts
- Disc and rim brake compatible with removable post cantilever pivots
- Upper seatstay threaded barrels with mid- and low-blade fully threaded through-blade fork eyelets

- Rohloff OEM2 axle plate mounting slot
- Tire clearance for 29 x 2.5” or 27.5 x 3”

The Surly Pugsley may be the original fat bike, but this one is far from the original. Previously a great all-around fat bike, the Pugsley has been redesigned to be an ideal off-road touring and exploration rig. Surly lengthened the chainstays 12mm for stability when loaded and so your heels float effortlessly past panniers. The tweaked rear rack mounts on the dropouts let you center your rack over the wheel, despite the offset rear triangle. Those dropouts will take a 142 x 12mm thru axle if that's your schtick, but can also be used with 135 x 10mmm QR hubs with Surly's Adapter Washers. Pugsley brings back the 135mm-spaced offset fork, so you can run a front wheel with a spare cog or freewheel as a bail-out option to swap with the rear if your internally-geared hub freezes up in neutral or you smash your derailleur having too much fun. A plethora of three-pack mounts give you gear-hauling options aplenty, so go wild with your build.
- 100% Surly 4130 chromoly frame, main triangle is double-butted; 1-1/8" threadless brazed chromoly fork
- Four sets of Three-Pack Mounts (two on the fork, two on the downtube), a water bottle mount on the seat tube, and front and rear rack mounts
- 142 x 12mm rear dropout (or 135 x 10mm QR with Surly 10/12 Adapter Washers) with Rohloff torque arm slot
- 135mm-spaced fork with 17.5mm offset for wheel swappability
- 26 x 4.8" tire clearance in frame (with drivetrain restrictions), 26 x 4.3" tire clearance in fork

Troll is a bike that has one purpose – and that purpose is to carry you as far away from society as possible. Man has known for eons the call of the indifferent forest. The inexorable march of time, and dumb things like cell phones, have dulled our senses and made us afraid. Reclaim your animalistic tendencies atop Man's greatest invention.

Off-road touring can be a zesty enterprise, but it’s not without its perils. Bicycles are simple machines that are extremely efficient, but all simple machines carry along with them the chance of breaking down. This efficiency can get you in trouble if your bike decides to break down far away from the comforts of your parent’s basement. If you’re going to ride your bicycles where no one can see, you better take gear that’s up to the task. Troll is up to the task.
Our Troll was once a simple mountain bike frame with a few extras that made it nice for touring. The Troll has evolved into a frame that has been pushed deeper into the category of off-road touring. Its geometry is no longer suspension corrected, which gives it more room for a larger frame bag. We’ve also adorned this frame with our Gnot-Boost spacing, allowing you to use any mountain bike hub whether it be 135mm QR, 12 x 142mm thru-axle, or 12 x 148mm Boost hub. The chainstay yoke has been redesigned to be fully compatible with 26+ tires and the dropouts still allow you to run disc brakes, fenders, a Rohloff hub, and racks simultaneously. It also comes with more braze-ons than you thought possible – there are four triple bottle mounts on the fork alone (don’t get excited, you can only run one Anything Cage per fork leg), as well as two more triple bottle mounts on the down tube.

BMC's Sportelite SE is a fun choice for rides to work, neighborhood cruising, and is your perfect entry into the world of trail riding. With 27 speeds courtesy of Shimano, you have plenty of reliable gears to choose from. A 100mm-travel fork absorbs the bumps and sidewalk curbs with ease. Lastly, the 27.5-inch wheels add that extra bit of confidence when just starting out. The bigger wheels roll over obstacles just a little bit easier. Your world will never be the same.

What does ECR mean? Anything you want it to. Go camping, ride the Divide Trail, disappear into the woods, and conquer any road. Surly's ECR is a super capable camping machine/trail bike that's outfitted to explore wherever you point the front wheel. Surly's favored chromoly tubing damps road buzz and provides a nimble, responsive ride. The heart of the ECR is the 29+ wheel capability, with clearance for 29 x 3.0-inch tires. Fat tires mean smooth-rolling traction, stability to spare, and a touch of suspension over the roughest terrain. On top of all that, frame eyelets galore are just waiting for racks, fenders, and whatever else to make this your pedal-powered escape pod.
